Let's divide 721604 by 55
We want to divide 721604 by 55.

Advancing to step 1:
55 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 55

Let's proceed to step 2:
55 goes into 72 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 55 from 72, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 55

Step 3:
55 can be fit into 171 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 165 from 171 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 55

Moving on to step 4:
The number 55 fits into 66 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 131.0
The remainder is 11 after subtracting 55 from 66.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 55

Moving on to step 5:
When dividing 110 by 55, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 1312.0
If we subtract 110 from 110, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 55

On to step 6:
If we divide 4 by 55, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 13120.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 55, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13120.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 13120.07
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
55 goes into 150 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 13120.072
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 55 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 13120.0727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
55 can be fit into 150 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 13120.07272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 13120.072727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
When dividing 150 by 55, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 13120.0727272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
55 can be fit into 400 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 13120.07272727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 13120.07272727 and a remainder of 1.5e-08.
